the japanese and english white quails are widespread strains and belongs to the galliformes order, phasianidae family, coturnix genus  and japonica species. these birds are likely to be well-adapted to the hard conditions and resistance to diseases as it has attained economic importance as an agricultural species. in the current study, the genetic variation of japanese and english white  quail ...

The current study was conducted to investigate the effects of genetic and non-genetic factors on body weight and carcass traits of Japanese quails. Two strains of Japanese quail (150 wild quails and 150 white quails) were used as base population. Four mating groups were used to produce progenies: wild male × wild female, white male × wild female, wild male × white female and white male × white ...

We evaluated messenger RNA (mRNA) expression of the growth-hormone (GHR) and insulin-like growth factor (IGF-1) genes in 28-day-old Japanese meat quails fed diets containing 0, 8, or 12% dietary glycerol in substitution of corn. Total RNA was extracted from the breast muscle and the DNA was amplified with specific primers using real-time PCR. Feed conversion ratio and feed intake were evaluated...

This study was undertaken to determine the effects of storage period and egg weight of hatching eggs of Japanese quails on fertility, hatchability results. Eggs were obtained 150 females quails, all at 15 weeks of age. A total of 1942 hatching eggs were separated into 3 groups as light-weight (9.50-10.50 g), medium-weight (10.5111.50 g), and heavy-weight (11.51-12.50 g). Based on storage period...

Response of Japanese quails to an inoculation of Schmidt-Ruppin strain of Rous sarcoma virus (SR-RSV) was examined. The quails were as susceptible as chick embryo cells to the infection of SR-RSV. The tumors induced in the quails contained a significant amount of infectious virus and avian leukosis group-specific CF antigen at early stages of 1 to 3 weeks after inoculation, but they turned to b...

This study was conducted to determine the effects of supplemented curcumin (CMN), derived from plant Curcuma longa, extract on performance and blood parameters of acetaminophen (ACT) induced quail hepatic injury. 240 quails from 0-37 days of age were used in a completely randomized design with 4 treatments of 4 replicates each and 15 chickens per replicate. All groups received 750 mg/kg body we...

This study was conducted to investigate the effects of garlic powder on the performance, egg traits, egg cholesterol and serum parameters of laying Japanese quails. One hundred and twenty 10-weeks-old quails were allocated to four dietary treatments. Quails were caged individually and fed diets supplemented with 0 (control), 1, 2, 4% garlic powder for 12 weeks. There were significant (P < 0.05)...

Helicobacter pylori (H. pylori) is a gram-negative, microaerophilic bacterium that cause the stomach infection in more than 50% of human population worldwide. The aim of this study was to examine the possibility of anti-H. pylori immunoglobulins Y (IgYs) production in quails and evaluate the effect of the different methods of immunization on titers of IgY in egg yolks. Whole cell bacterial anti...

Induction of agammaglobulinemia in Japanese quails was attempted by various procedures of bursectomy (BX) including hormonal BX (H-BX) with testosterone, surgical BX (S-BX), chemical BX (C-BX) with cyclophosphamide and irradiation with gamma-ray. Immunosuppressive effect of BX was evaluated by antibody production in response to immunization with bovine serum albumin and sheep red blood cells, b...
